Before this change if Layout dialect not available then the nested class is
loaded and barfs because it depended on the layout dialect (in a
@ConditionalOnClass annotation).
* The TraceAutoConfiguration in the service project
was loading too early because it contains a BPP
* It also had a Spring Security dependency without any
@Conditional* configuration
* Fixed by nesting the BPP in a class with @Conditional*
* Use file adapters in sample instead of internal flow
* Add Exception to signature of CommandLineRunner for
implementation convenience
* Updates for Security snapshots
* Added a test for each of the classes loaded by the SpringApplication
* If it's an anonymous class or looks like a Groovy closure we ignore it
* The CLI sample job.groovy also modified to take advantage
[Fixes#48718891]
* Also added "spring" shell script (in zip), so you can
unzip it and run out of the box
* To run in developer mode use SPRING_HOME, e.g.
$ cd spring-bootstrap-cli
$ SPRING_HOME=target src/main/scripts/spring run samples/web.groovy
* Also added "clean" command to remove spring bootstrap grapes
(useful to force a refresh of snapshot jars)
